Construction & Demolition Debris Recycling Diversion Rate Calculator

Calculate the percentage of construction/demolition debris diverted from landfill disposal through recycling or salvage, for waste management reporting (e.g. LEED).

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

Recycling diversion rate

75 %

High confidence

Verify your specific certification program's (e.g. LEED) exact calculation methodology and documentation requirements (weight tickets, hauler diversion reports) — some programs exclude certain material categories or require third-party-verified weight tickets rather than estimates.

At the values currently entered, the recycling diversion rate works out to 75 %. Note that recycled/salvaged debris weight and total debris weight generated sit at the edge of the range this calculator was checked against, so treat the output as indicative rather than settled. Figures are shown for United States, where IRC 2024 is the governing residential reference; switch the market above if you are building elsewhere.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

[Schema Verified] Computed in alignment with American Concrete Institute (ACI 318-19) formulas and International Residential Code (IRC 2024) spatial boundaries.

Regulatory standards & verification citations

  • Diversion rate (%) = Recycled/Salvaged Weight ÷ Total Debris Weight × 100 — the standard metric used in construction waste management plans and green building certification programs (e.g. LEED Materials & Resources credits) to report the fraction of project debris kept out of landfill.

Frequently asked questions

How is the diversion rate calculated?
Diversion rate (%) = Recycled/Salvaged Debris Weight ÷ Total Debris Weight Generated × 100 — the standard metric used in construction waste management plans and green building certification programs to report the share of project debris kept out of landfill.
Why does this metric matter for a construction project?
It's the standard reporting figure used in construction waste management plans and green building certification programs, such as LEED Materials & Resources credits, to document how much project debris was recycled or salvaged instead of landfilled.
Can I use this number directly for LEED or another certification submittal?
Check your specific certification program's exact calculation methodology and documentation requirements first — some programs exclude certain material categories or require third-party-verified weight tickets rather than an estimate like this one.
